Psalms 86:2

Preserve my soul; for I am holy: O thou my God, save thy servant that trusteth in thee.

The psalm containing the saying, including the saying itself, is a psalm of David and a prayer of David. It was also identified as a psalm of the sons of Korah rather than as David's. It belongs to the Bible's treasure of comfort and consolation for God's children.

The word rendered holy usually means merciful, or pious and godly, rather than holy. Its root carries the sense of kindness, love, or zeal toward someone. The saying can therefore be read as the speaker appealing to his own mercy toward others as he asks God for mercy, though the word was sometimes understood as holy.

The saying is a prayer asking God to preserve the speaker's life or soul and to save him because he belongs to God and trusts in him. The appeal to holiness expresses confidence of having acted with integrity in the conflict with enemies. Such a humble plea for preservation and rescue from enemies gives confidence in seeking deliverance from wicked and proud enemies.
